PROBLEM TO BE SOLVED: To provide a construction method for a loading test pile which is so constituted as to surely place concrete of a reaction pile and a test pile by dividing into the top and the bottom. SOLUTION: This loading test member is so constituted that a partition plate is provided in the lower end of a load transmission member, the upper end side of a jack for both pushing and pulling is fixedly provided in the bottom face of the partition plate, the load transmission member transmitting the load to the test pile is fixedly provided to the lower side of the jack, the blower end of the guide pipe is made to penetrate through the partition plate, and the upper end is erected upward of the top setting position of the reaction pile. This loading test member is inserted into a pile hole excavated the ground. A tremie pipe is made to pass through eh guide pipe, inserted into the concrete placing position of the test pile, and concrete is placed in the lower part of the partition plate till the necessary height to constitute the test pile.
